.To aZZ whom t may concern:

Be it known that I, JAMES S. SHORTLE, a citizen of the United States, residing at Ghicago, in the county of Cook and State of Illinois, have invented a new and useful Improvenienti in SiphonfI-Ieads, of which the :tol-Y lowing is a speciiication.

My invention relates to siphon-heads for vessels in which liquids are stored and discharged under gas-pressure.

The objects of my invention are to attain simplicity and cleanliness in devices of this class; to provide a Siphon-head which will be operative without the spring and springchamber in ordinary use on devicesof this class, one which maybe operated with a lower gas-pressure than is required by those in ordinary use, and one in which the entire body of the Siphon-head is of such simplicity that it can be readily molded from glass, porcelain, or similar material; to provide for cleanliness by arran gin g the valve-actuatin g mech-V anism mainly outside of the body of the siphon-head; to provide for adjusting the valveactuating mechanism out of the operative position, so as to avoid accidental discharge of the liquid, and to improve the construction of the valve and its actuating mechanism. 'I accomplish these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure l is a vertical section of the upper part of a bottle l0, having a Siphon-head constructed according to my invention secured thereto. The valve is closed `in this vieur and the lever is shown in dotted lines laid back out of the operative position. Fig. 2 is the same view showing the valve open for the discharge of fluid. Fig. 3 is an outside view of the valve with its stem and the elastic collar 4.

The casing i' or body of the Siphon-head has the valve-chamber therein, is provided with a discharge-chamber terminating in the nozzle 7", and a projection 6, furnishing a fulcrum-seat for the lever.

The casing 7 is suitably arranged for attachment to the vessel. This may be done by means of the divided collar 11, such as is in ordinary use, or it maybe attached in any other convenient manner. It will be understood that same maybe adapted for attachment toany desired form of vessel.

The tube 9 is heldin an elastic hollow plug 8, having an annular recess for the iiange on tlie tube and having an outer flange around the top of the plug serving as a gasket or packing between the top of the bottle-neck andthe casing 7. The iiange on the tube and the annular recess for same in the plug may' be omitted, the lateral pressure of the plug on the tube being usually sufficient to hold saine in position. The object of this form of plug is to bring the top of the tube down substantially iiush with the bottle. This is an advantage over those in ordinary use, Where the tube projects into the valve-chamber and the valve operates in an enlargement of the tube. struction Without enlarging the body of the Siphon-head.

The valve l 2 is seated in the upper part of the chamber 7 and controls the passage from the vessel into the nozzle '7". Thevalve is provided with a stem 3, extending through the top of the casing and having thereon a head 3. Intervening the head 3' and the top of the casing is the elastic packing or collar 4, through which the stem 3 extends. This serves both as a spring for normally closing the valve and as a gasket or a packing for the valve-stem. The lever 5 has its fulcrum in the projection 6. The projection 6 preferably extends higher than the head 3, so that when the lever is laid back in the position shown by the dotted lines the bottles may be packed The valve consists oi' the body l, of metal or some other hard material, having an annular recess, into which the elastic disk 2 is sprung. The piece l is threaded upon the stem 3, thus providing for ready attachment of the parts, as Well as for adjustment of the valve either before or after the Siphon-head is secured to the vessel. This is done by turning the head 3', thereby screwing the stem in the body 1 of the valve. When the valve is closed, the disk 2 will be bent downwardly at its outer rim through its contact with the Walls of the upper narrow part of the chamber 7. The lower liange on the member l,

formed by the annular recess, is prei'erablyl beveled ontop, so that same rmly presses the A larger vent is provided in my conyIO ythe valve is closed.

disk against the walls of the chamber when The nozzle is preferably made so that it will slant downwardly from the top of the valve toward the discharge end. This prevents an accumulation of liquid above the valve. My valve is particularly adapted for this purpose,since.the elasticity of the disk 2 permits the upper part of the valve to be drawn up flush with the lower wall of the discharge-chamber or with the base of the nozzle. The elasticity of the disk 2 also provides a broad Contact of the valve with the walls of the upper part of the chamber 7', thus furnishing a very secure valve, requiring butlittle pressure to hold it in position.

I regard it as a particular advantage in my device to have the valve-actuating mechanism mainly on the outside of the Siphon-head, so that the parts may be easily kept clean.

A feature of my valve connection is that the valve may be tightened from the outside by turning the head 3', thus providing a further safeguard against accidental discharge of the fluid in shipping. This, it will be seen, can be readily loosenedagain by the operator, so as to permit the free operation of the Siphon.

The disk 2 is preferably made of rubber, and the contact of this with the walls of the chamber 7 prevents the body of the valve from turning when the stem is turned in the member l. f

It will be seen that a spring may be used in connection with my member 4; but I prefer to use this member without a spring, first, on account of cleanliness,and,second,because but little force is needed to close the valve, the same being held in position principally by the pressure of the gas.

The elastic members 2, 4, and 8 may be readily replaced by others when worn or hardened through the action of the fluid or gases.

The other parts of the device may be made of metal or any other suitable material,such as porcelain. The simplicity of the member 7 par-- ticularly adapts same to be made of porcelain. lVhat I claim as my invention, and desire to secure by Letters Patent, is-
